Your story brings back memories. I bought my first radio in 1953. It was a Berkeley Airtrol that I never got working reliably enough to risk a flight before going in the Air Force a few months later. In 1956, I was transferred to Tyndall AFB where I met the late Jim Kirkland. He was flying RC so I bought the same equipment he was using. It was a Lorenz 2-tube receiver, Southwest magnetic actuator, and a rotating drum pulse controller. With help from Jim, I soon made my first successful flight. The rotating drum control box made it truly proportional, at least until the drum quit rotating. The drum was driven by a mighty midget motor through a gear train. The stick on the control box moved a wiper along the drum. At one end, very short pulses were sent out while at the other end, a solid signal was transmitted. The gears were very noisy so it was quite a shock when the noise stopped when I gave full rudder. The drum wiper had slid off the end of the drum and jammed the gears. Some frantic banging on the box un -jammed the gears before the model spiraled into the ground. I modified the control box to prevent that happening again before the next weekend.

You are right. They are some wonderful memories that make me really appreciate what I have today.

For the younger fliers, Jim Kirkland was one of the top RC fliers in the 60's and early 70's. Shortly after retiring from the Air Force, he suffered a fatal heart attack while unloading a 55 gallon drum of model airplane fuel.

Hey, guys we actually did have airplanes similar to what you describe in the
early days. Full on full off controls and limited flight functions. We did
have to put in much more effort to get airborne than just "open a box"
however.  :^0

My first experience in RC was back in high school. Where a neighbor and my
memory is vague on this, but I believe his name was Bob who was an
electrical engineer at Texas Instruments,  helped me get started in this
wonderful hobby. Without his help it may never had happened. The system he
selected for me to put together comprised an Ace Commander transmitter with
the pulse conversion kit, which I assembled that he debugged and tuned, a
Citizenship SSH single channel receiver and an Adams Dual magnet actuator.

I can remember at least a couple of nights in his shop, him at the
oscilloscope and me walking up and down the alley with the debugged and now
functioning x-mitter, tuning the receiver. This equipment was installed in a
Top Flight Schoolmaster with a Cox Medallion .049. BTW, at his urging, I
built the Schoolmaster without the landing gear to reduce weight which
really seemed weird to me at the time. In flying mode the engine ran and the
airplane climbed until it was out of fuel. The airplane was trimmed to climb
under power and glide without zooming up or down in each flight mode. To
prevent a zoom and subsequent stall rudder inputs were used to turn the
aircraft out of the zoom before the stall occurred.

The Adams actuator provided rudder only control. The rudder banged from side
to side continuously at neutral and we found later that the best control was
available by using the full right/left buttons, even though the conversion
kit supposedly provided "proportional control". How long the button was held
determined the amount of control input. The radio gear, with assembly
manuals, and the engine are still with me in my "can't throw out box".

Many days of wonder and enjoyment watching and flying that airplane are
still in my memories. Now that I know what I know about thermal soaring I
had some flights where I thermal soared that little rig. Yes, the initial
days of trimming and setup were frustrating for a young man in high school,
but it taught me what is required to successfully accomplish a complex
project. This is lacking in our now instant gratification society, aka, just
hit the reset button and all is repaired.

It was truly different many years later after college when I came back to
the hobby and bought my first four channel proportional radio system for
only about twice as much as I spent on that original radio! With all the
wonderful memories, challenges, and accomplishments this hobby has provided,
I am truly indebted to that neighbor.

Hope all had a wonderful Christmas and your New Year is to your
expectations. Now to go out and fly it's supposed to be in the 50's today
with light winds here in Texas.
